敦煌阳关国家级自然保护区生物多样性及保护对策分析

Analysis on the Biological Diversity and Protective Strategy in Nature Reserve of Yangguan in Dunhuang China

地处西部荒漠和戈壁中的敦煌阳关国家级自然保护区作为重要的候鸟迁徙驿站和栖息地,是一个天然的动植物博物馆和基因库。保护区特殊的地理环境下的多样的生物对我国西部极干旱地区生物多样性方面的科学研究具有一定价值。然而,随着生态环境逐渐恶化,该地区生物多样性受到了如栖息地逐渐缩小和破碎、掠夺式过度利用等人为因素及自然因素的威胁和限制。本文分析了该保护区内生物多样性现状及多样性保护面临的问题,并提出了相应的保护对策,以期对今后保护区的物种多样性保护工作具有一定的作用。

The biodiversity protection has become one of three environmental problems from the worldwide focused on. Nature Reserve of Yangguan in Dunham( NRYD),which is located in the furthest western of China,is a natural museum and gene pool of animals and plants. And NRYD is one of the most important areas for protection and science research of value. Whereas,the biodiversity is under threat and restriction due to shrinking habitat,fragmentation,over utilization,poaching,natural disasters,unclear protection objective,weak technology,insufficient fund,unclear basic resources as well as poor public awareness and so on. Aiming at these problems,some protection strategies are put forward,and uill provide guidance for the biodiversity protection work in the NRYD.
